To optimize the hydrogenation process and produce a product whose quality conforms to the hydrogenated vegetable oil type I in the US Pharmacopoeia (USP 24), a central composite design was applied. The influence of three main process parameters, i.e. amount of catalyst, hydrogen pressure and ...
After the initial process design is completed, the DMO hydrogenation process is optimized to obtain the optimal design with the minimum total annual cost (TAC). During process optimization, it is found that the mole ratio of hydrogen to DMO (HDMR) has global influences on TAC, and thus it ...
The optimization was conducted based on hourly meteorological data at Ordos, Inner Mongolia, China, as well as the hydrogen and electricity consumption by the downstream CO2 hydrogenation unit. On top of that, an integrative techno-economic analysis was conducted on the entire green methanol plant....
Transient multiphase systems Model-based optimal experimental design Mechanistic kinetics Parameter estimation Hydroaminomethylation Dynamic optimization 1. Motivation Aliphatic amines are essential for the production of agrochemicals, surfactants, herbicides and pharmaceuticals [1], [2]. From the total annual ...
Ceramic fuel cells offer a clean and efficient means of producing electricity through a variety of fuels. However, miniaturization of cell dimensions for portable device application remains a challenge, as volumetric power densities generated by readily-
methanation of carbon dioxide [21], CO hydrogenation to methane (CH4) [22], CO oxidation to CO2 [23], hydroformylation using syngas [24], hydrogenation reactions [25], synthesis of low valent Mg (I), p-block, and group 15 complexes [26,27,28]. BM assists in the generation of new ...
Optimization of ex-situ biomethanation process in trickle bed reactor: The impact of slight H2/CO2 ratio adjustments and different packing materials This study aimed to evaluate and optimize trickle bed reactor (TBR) performance for biological biogas upgrading at different gas loading rates (10-35 ...
the three-dimensional structure of PSP•at 1.8 Å resolution by X-ray crystallography. Genetic engineering enabled the site-specific attachment of a nickel–terpyridine complex and the modular optimization of the photochemical properties of PSP, the chromophore/catalytic centre distance and the cata...
2. The four major blocks in the proposed process are the N2 separation unit, the tri-reforming reactor, the DME production, and the DME purification section. Optimization of operating conditions for tri-reforming and DME synthesis reactors The whole process was simulated using Aspen Plus 7.3. ...
Hydrotalcite and its derivatives are widely used in catalytic hydrogenation, organic conversion, water splitting, and other fields. Supported catalysts are very important for modern industry. A large number of experimental and theoretical studies have shown that the carrier in the supported catalysts not...
